In this paper we propose a compositional semantics for lexicalized tree-adjoining grammar (LTAG). Tree-local multicomponent derivations allow separation of the semantic contribution of a lexical item into one component contributing to the predicate argument structure and a second component contributing to scope semantics. Based on this idea a syntax-semantics interface is presented where the compositional semantics depends only on the derivation structure. It is shown that the derivation structure (and indirectly the locality of derivations) allows an appropriate amount of underspecification. This is illustrated by investigating underspecified representations for quantifier scope ambiguities and related phenomena such as adjunct scope and island constraints.

We propose a semantic construction method for Feature-Based Tree Adjoining Grammar which is based on the derived tree, compare it with related proposals and briefly discuss some implementation possibilities.

The definition of similarity between sentences is formulated on the levels of words, POS tags, and chunks (Abney 91; Abney 96). The evaluation of this approach shows that while precision and recall based on the PARSEVAL measures (Black et al. 91) do not reach state of the art Parsers yet (F1=87.19 on syntactic constituents, F1=77.78 including functionargument structure), the parser shows a very reliable performance where function-argument structure is concerned (F1=96.52). The lower F-scores are very often due to unattached constituents.

The earliest known extensive texts in Gullah (and perhaps African American Vernacular English as well) to appear in print were published in The Riverside Magazine for Young People in November, 1868, under the title "Negro Fables" (p. 505-507). These are four animal stories, which the editor of the magazine, Horace Elisha Scudder, described in his column only as having been "taken down from the lips of an old negro, in the vicinity of Charleston" (see Appendix for the editor´s comments and the full text of the stories).2 The Story-Teller was evidently a genuine "man of words" (Abrahams, 1983), a true raconteur who could artistically embellish a simple traditional account (perhaps further embellished by the transcriber) in a variety of ways. That he commanded a certain range of Gullah is evident from particular signature features in the texts, but the absence of other typical Gullah features and the presence of shared Gullah/African American Vernacular English usages, together with the periodic appearance of standard English forms, demonstrate that these texts provide perhaps the earliest actual documentation (apart from early tertiary comments, cited e.g. in Feagin, 1997, p. 128-129) of register variation or style/code-switching among Gullah speakers. ...

Semantic research over the past three decades has provided impressive confirmation of Donald Davidsons famous claim that “there is a lot of language we can make systematic sense of if we suppose events exist” (Davidson 1980:137). Nowadays, Davidsonian event arguments are no longer reserved only for action verbs (as Davidson originally proposed) or even only for the category of verbs, but instead are widely assumed to be associated with any kind of predicate (e.g. Higginbotham 2000, Parsons 2000).1 The following quotation from Higginbotham and Ramchand (1997) illustrates the reasoning that motivates this move: "Once we assume that predicates (or their verbal, etc. heads) have a position for events, taking the many consequences that stem therefrom, as outlined in publications originating with Donald Davidson (1967), and further applied in Higginbotham (1985, 1989), and Terence Parsons (1990), we are not in a position to deny an event-position to any predicate; for the evidence for, and applications of, the assumption are the same for all predicates. (Higginbotham and Ramchand 1997:54)" In fact, since Davidson’s original proposal the burden of proof for postulating event arguments seems to have shifted completely, leading Raposo and Uriagereka (1995), for example, to the following verdict: "it is unclear what it means for a predicate not to have a Davidsonian argument (Raposo and Uriagereka 1995:182)" That is, Davidsonian eventuality arguments apparently have become something like a trademark for predicates in general. The goal of the present paper is to subject this view of the relationship between predicates and events to real scrutiny. By taking a closer look at the simplest independent predicational structure – viz. copula sentences – I will argue that current Davidsonian approaches tend to stretch the notion of events too far, thereby giving up much of its linguistic and ontological usefulness. More specifically, the paper will tackle the following three questions: 1. Do copula sentences support the current view of the inherent event-relatedness of predicates? 2. If not, what is a possible alternative to an event-based analysis of copula sentences? 3. What does this tell us about Davidsonian events? The paper is organized as follows: Section 2 first reviews current event-based analyses of copula sentences and then gives a brief summary of the Davidsonian notion of events. Section 3 examines the behavior of copula sentences with respect to some standard (as well as some new) eventuality diagnostics. Copula expressions will turn out to fail all eventuality tests. They differ sharply from state verbs like stand, sit, sleep in this respect. (The latter pass all eventuality tests and therefore qualify as true “Davidsonian state” expressions.) On the basis of these observations, section 4 provides an alternative account of copula sentences that combines Kim’s (1969, 1976) notion of property exemplifications with Ashers (1993, 2000) conception of abstract objects. Specifically, I will argue that the copula introduces a referential argument for a temporally bound property exemplification (= “Kimian state”). The proposal is implemented within a DRT framework. Finally, section 5 offers some concluding remarks and suggests that supplementing Davidsonian eventualities by Kimian states not only yields a more adequate analysis for copula expressions and the like but may also improve our treatment of events.

This short overview reviews, in the first part, some of the most important fields of investigation where studies on Galician have contributed to variational linguistics, including macro- and micro-sociolinguistic studies (sections 1-3). The second part (sections 4-7) postulates some possible theoretical and empirical areas which we recommend to be included in future research. We propose a critical application of new models of linguistic variation, including recent frameworks such as studies on grammaticalisation, OT, intonational phonology, etc., but also call for the inclusion of established insights into language variation common in the European tradition. The high concentration of research institutions and the strongly dynamic situation of contemporary Galician could serve as an empirical touchstone for these theoretical frameworks, and Galician linguistics should apply them in a critical, flexible and creative way. This means that research on Galician will not only learn from theory but also contribute to it. We also briefly mention some of the areas where the studies of Galician have already contributed some important results to an overall perspective on linguistic variation.
